Thread sealed the return fitting and tightened up.  Removed the tank from the wing, added a small section of fuel line to the return and clamped it off.  Clamped the end of the main line too.  Added 20 litres of unleaded to test (placed the tank in the carport next to the car, figured after the test I can just drain it into the car!)

Seems to be no leaks around the fitting at the moment, will give it a full 24 hours or more just to make sure.

Received the quick-disconnect fittings and installed them on the root rib, however I think the lines will be blocked by the cabin frame - might have to create a mounting position just inside the root rib in order to give the line enough room to miss the cabin frame.

Hi Gary,

I used Loctite 2 Gasket Sealant - comes in a 3oz (85g) tube similar size to toothpaste.  It has another number - 30514.

The boys at Repco took quite a while choosing which product was suitable when I told them what I wanted it for, it seems to have worked so far - hope it continues to!

Curious to know what you are using for thread seal. My tanks have a very slight leak now where the brass fitting screws into the tank.
